    Abstract: A fuel system (10) for a gas turbine engine that improves efficiency by supplying fuel to a primary stage (14) and secondary stage (16) via a common fuel source (18) is disclosed. The fuel system (10) may be formed from first and second primary injector assembly stages (20, 22) and a first premix injector assembly stage (24) positioned upstream from a combustor chamber (26), whereby the first premix injector assembly stage (24) is a secondary injector system. The second primary stage (22) and the first premix stage (24) may be in fluid communication with the same fuel source (18) to eliminate duplicative components found within systems where fuel is supplied individually to the second primary stage and the first premix stage. In at least one embodiment, the second primary injector assembly stage (22) and the first premix injector assembly stage (24) may each be in communication with a fuel manifold (28) configured to supply more fuel to the second primary stage (22) than the first premix stage (24).

    Abstract: A dual stage vane pilot nozzle (100) has a non-diffusion nozzle (110) and a first fuel stage (121) and a second fuel stage (122). The first fuel stage (121) has a first fuel injector (101) having first injection holes (103) and a first fuel annulus (105). The second fuel stage (122) has a second fuel injector (102) having second injection holes (104) and a second fuel annulus (106). The non-diffusion (110) does not have a diffusion tip. This arrangement allows for the reduction of nitrogen oxide emissions.

    Abstract: A transition duct exit frame (10) for supporting a transition duct (12) extending downstream from a combustor (14) to a turbine assembly (16) in a gas turbine engine (18) and including one or more transition duct exit frame inserts (20) configured to reduce thermal distortion created during operation of the gas turbine engine (18) is disclosed. The transition duct exit frame (10) is formed from one or more transition duct exit frame bodies (22). The transition duct exit frame body (22) is formed from a first material having a first coefficient of thermal expansion. The transition duct exit frame insert (20) forms at least a portion of the transition duct exit frame body. The transition duct exit frame insert (20) is formed from a second material (26) having a second coefficient of thermal expansion that is different than the first coefficient of thermal expansion of the first material (24) to reduce distortion within the transition duct exit frame body (22) during operation of the gas turbine engine (18).
